To be fair to Trump, it is the first time that anyone has tried to manage an entire economy with tweets. Not the first time a leader has tried to make friends rich and opponents poor, just the first time to do it 140 characters at a time.
Feudalism, communism, capitalism ... twitterism? Twitocracy? Not sure what to call it but it is a fascinating new development in economics.
I'm trying to influence the small economy of Estonia with tweets but so far to no avail. I'll continue to experiment and report back once I've collected data.
